Dallas Semiconductor's DS1371 2-wire watchdog clock combines a 32-bit binary counter, periodic alarm, and programmable square-wave output in a small 8-pin microSOP package. Small size and low-voltage makes it ideal for portable and battery-powered systems. The 32-bit counter increments once per second, from which a software algorithm computes time of day, date, month, and year. An additional 24-bit counter can generate a periodic alarm or serve as a watchdog timer. If enabled as a watchdog timer, the watchdog strobe input pin provides a hardware reset of the counter. A configurable output can be used as an interrupt or provide a square wave at one of four selectable frequencies. Address and data are transferred serially through a 2-wire bus that operates from 1,7 V to 5,5 V. The oscillator keeps time while operating down to 1,3 V, consuming less than 500 nA (typ). Operates over -40 to +85°C.
